In modern industrial equipment, hydraulic pump stations play a central role. Whether it's a home elevator, a car repair lift, or the drive system of large machinery, the hydraulic pump station is a crucial unit for power output. For companies engaged in equipment manufacturing, construction machinery, building construction, or automation system integration, choosing a suitable hydraulic pump station not only affects production efficiency but also directly impacts equipment safety and lifespan.
| Components | Functional Description | Selection Considerations |
| Hydraulic Pump | Provides system pressure and flow | Selection based on pressure, flow rate, and oil type |
| Electric Motor | Drives the hydraulic pump | Power and speed must be matched |
| Tank | Stores hydraulic oil, dissipates heat, and settles impurities | Capacity is typically 3-5 times the pump flow rate |
| Valve Group | Controls oil direction and pressure | Combinations of solenoid valves, relief valves, and throttle valves are selected |
| Filtration System | Keeps the oil clean and prevents wear | Filtration accuracy is recommended to be ≤10μm |
| Piping & Fittings | Connects various components and transmits oil | Pressure rating and sealing performance must be considered |
The hydraulic pump station uses a motor to drive the hydraulic pump, which draws hydraulic oil from the tank and pressurizes it into the system pipelines. After being regulated by the control valve group, it is delivered to the actuators to achieve lifting, pushing, pulling, and rotating actions. The system returns the hydraulic fluid to the tank via a return oil circuit, forming a continuous closed loop.
Among Oudi's wholesale hydraulic pump stations, different models are precisely configured for flow rate, pressure, and temperature control, meeting the needs of various industrial applications such as elevators, lifting platforms, and die-casting equipment.
Parameter matching is the most critical step when purchasing a hydraulic pump station. Incorrect selection may lead to increased energy consumption, system overheating, or even equipment damage. The following are several key technical parameters to focus on when purchasing.
The rated pressure of the hydraulic system determines the output capacity of the equipment. Generally, the rated pressure range of common hydraulic pump stations is between 6MPa and 35MPa. Selection must be based on the design pressure of the equipment's actuators.
Low-pressure systems (≤10MPa): Suitable for small lifting equipment and experimental equipment.
Medium-pressure systems (10–25MPa): Commonly found in automotive repair lifts and industrial machinery.
High-pressure systems (≥25MPa): Used in construction machinery, die-casting equipment, or heavy-duty equipment.
Oudi hydraulic pump stations utilize high-precision relief valves and imported seals to ensure stable operation under high-pressure conditions.
Flow rate determines the operating speed of the hydraulic cylinder or motor. It is usually calculated using formulas to match the volumetric velocity of the actuator, but the following suggestions can be used as a reference during selection: Lifting equipment: Flow rate should be 10–40 L/min; Industrial automation machinery: Flow rate should be 5–25 L/min; High-speed operating equipment: Flow rate can reach 60 L/min or higher. Choosing an excessively large flow rate will result in energy waste, while insufficient flow rate will lead to sluggish operation and reduced efficiency.
Motor power must be matched with the hydraulic pump's displacement, pressure, and efficiency. Three-phase asynchronous motors are typically used, with power ranging from 0.75kW to 22kW.
When supplying hydraulic pump stations wholesale, Oudi offers customized motor and pump unit matching solutions based on customer load requirements.
The tank capacity should typically be 3–5 times the pump flow rate to ensure sufficient heat dissipation and settling space. For continuous operation or high-load systems, air-cooling or water-cooling is recommended.
Tip: When the pump station operates under high load for extended periods, Oudi hydraulic pump stations with independent cooling systems should be prioritized to maintain stable oil temperature and extend service life.
Besides technical parameters, the structural layout and control system design of the pump station also affect performance and ease of maintenance.
Based on application and installation method, hydraulic pump stations can generally be divided into the following structural types:
Vertical Type: Small footprint, suitable for space-constrained equipment, such as home elevators.
Horizontal Type: Sturdy structure, good heat dissipation, suitable for large equipment.
Modular Type Pump Stations: These can be flexibly expanded to meet system needs and are commonly used in automated production lines.
Oudi's wholesale hydraulic pump station products cover various structural designs and support customer customization to adapt to different installation spaces and working conditions.
The control system of a hydraulic pump station determines the ease of operation and the degree of automation. Common control methods include:
Manual Control: Simple and reliable, suitable for equipment with single-action functions.
Electromagnetic Control: Enables remote operation via solenoid valves, commonly found in elevators and lifting platforms.
PLC Control: Suitable for automated systems, enabling multi-action logic control.
Proportional Control and Servo Control: Suitable for high-precision applications, such as CNC machine tools and die-casting machines.
Oudi's hydraulic pump station control systems support multiple voltage standards (AC220V, 380V, DC24V) and can integrate a PLC interface for easy connection to the main control system.
Hydraulic pump stations are prone to noise and vibration during operation. High-quality products utilize:
Rubber vibration-damping base
Low-noise gear pump
Double-layer soundproof enclosure design
Optimized flow path to reduce oil pulsation
This not only enhances the user experience but also meets industrial safety standards.
The cleanliness of the hydraulic oil is crucial to the lifespan of the pump station. Excessive impurities can lead to valve sticking, pump wear, and even system failure.
Regular oil changes and the use of high-precision filters are recommended.
Hydraulic systems generate heat during operation. If the oil temperature exceeds 70°C, the oil viscosity decreases, weakening lubrication. Temperature should be controlled by installing an oil cooler or using a large-capacity oil tank.
Monthly checks of oil level and quality
Six-monthly filter replacement
Annual inspection of seals and pipe joints
Oudi hydraulic pump stations undergo rigorous testing before wholesale shipment, including pressure testing, sealing testing, and noise testing, ensuring stable and reliable operation for users over the long term.
In summary, when purchasing a hydraulic pump station, a comprehensive evaluation should be conducted considering multiple dimensions, including performance parameters, structural control, operating environment, and supplier capabilities. Correct selection not only improves equipment efficiency but also effectively reduces maintenance costs and extends equipment lifespan.
